What to Expect During Your Sleep Study

Preparing for your sleep study

An all-night sleep study is valuable for diagnosing and treating many sleep disorders, including breathing, movement and neurological disorders that happen while you're asleep. Sleep studies are easy to tolerate, comfortable and give the sleep physician the information needed to accurately diagnose and treat your sleep disorder.

ProHealth Care Sleep Center

ProHealth Care has opened a new state-of-the-art Sleep Center located near Hwys. 94 and 83 in Delafield. The location is 2301 Sun Valley Dr (the First Heritage Drive just south of 83), Delafield, WI 53018. It is located on the 3rd floor, Suite 300.

You'll meet with the sleep technician who will explain and perform your study. Shower facilities are also available. And a continental breakfast will be provided in the morning. Accommodations can be made for second and third shift workers.

Getting ready for bed

We will apply electrodes to your scalp, sides of your head, under your chin and on your chest. This lets us measure brain waves, heart rate and eye movements while you're sleeping. We'll also place a sensor by your nose and mouth to measure airflow. Belts are placed around your rib cage and abdomen to measure breathing movements. A clip is placed on your finger to measure your blood oxygen levels.

There are no needles and no pain

The electrodes are connected to a box by the bedside for relaying the signals to the central control room. In addition, all patients are videotaped while sleeping.

In the central control room, the technician monitors your sleep and general condition. You can easily call the technician if there is any problem.

Special needs for sleep apnea

For some patients with sleep apnea, the effects of continuous positive airway pressure (CPAP) are evaluated. Usually these patients have had a previous sleep study to diagnose the condition. During the CPAP study, everything is done the same as a normal sleep study. In addition, a mask is fit around the nose or nose and mouth. During sleep, the technician attempts to find a pressure level that holds the airway open and lets the patient get a good night's sleep.

Time to get up

Your sleep study should be completed and you should get to go home by 6 or 7 a.m. However, if you need to wake up earlier, just let the technician know.

Once your sleep study is completed, it's scored and sent to a sleep physician for interpretation. The interpretation is sent to the physician who ordered the sleep study and appropriate follow-up is arranged.
